Abstract (en)

[origin: US2019311131A1] A method may include obtaining, from a runtime system that executes code, a source value at a source point of the code and a sink value at a sink point of the code, identifying a potential taint flow from the source point to the sink point by performing a series of taint inferences that each infer a relationship between the source value and the sink value, and determining whether the potential taint flow is an actual taint flow by performing a series of taint checks that each analyze the execution of the code using the source value and the sink value.
